[Rhythmic bioelectrical activity of the cerebral cortex analyzed with allowance for the nonlinear voltage dependence of excitatory postsynaptic potentials induced by neocortical neurons].
A nonlinear voltage dependence between the membrane and excitatory postsynaptic potentials coming via corticocortical connections was derived based on literature data. The existence of a region of stability of oscillations with increasing mean value of nonspecific afferent input was shown. As the afferent input strongly increases, a high-frequency component of oscillations (40-60 Hz), appeas which may result in the instability of oscillations and initiation of abnormal brain activity.
